Abstract
Based on the failure criterion that is suitable for the undirectional composite laminates, the impact damage of fabric fiber reinforced composites is proposed to improve the fiber and matrix damage failure criterion. The impact damage of longitude fiber failure, latitude fiber failure, matrix crushing and delamination were considered for the fabric carbon fiber reinforced epoxy composites laminates. A finite element analysis model is established by using ABAQUS software combined with the sudden stiffness degradation model. Basic strength parameters of composites are used to evaluate the mechanical properties of CFRP laminates with different porosities. The impact damage area of the fabric carbon fiber reinforced epoxy composites laminates are simulated accurately.
